About Psi Quantum
Company building a photonic quantum computer based on silicon photonics, aiming for a million-qubit machine. Raised $1B in a Series E in September 2025 at about a $7B valuation led by BlackRock, Temasek, and Baillie Gifford.
PsiQuantum is building a quantum computer on single particles of light. The chips are printed at a commercial semiconductor fab, and the goal is a million-qubit machine. Founded in 2016 in Palo Alto. The first two industrial sites are already under construction, in Queensland and Chicago: work began at Moreton Bay on the site of a former paper mill on June 17, 2026. In July 2026 Victor Peng, former president of AMD and head of Xilinx, became CEO, while founder Jeremy O'Brien moved to executive chairman; in April, Intel CEO Lip-Bu Tan joined the board. Current valuation is $7B from a Series E (September 2025); $1.67B raised across five rounds since 2016.

Key highlights
- The US government came in with a stake, not a grant. In May 2026 the Department of Commerce distributed $2B under the CHIPS program across nine quantum companies, taking non-controlling equity stakes in return; PsiQuantum signed a letter of intent for $100M.
- DARPA moved the company into the final phase of independent verification. In July 2026 the agreement was expanded to $125M under Stage C of the quantum benchmarking program, after $31.8M in September 2025.
- Leadership has been rebuilt for industrial scale. In July 2026 Victor Peng, former president of AMD and head of Xilinx, became CEO, while founder Jeremy O'Brien moved to executive chairman; in April, Intel CEO Lip-Bu Tan joined the board.
- The first industrial site has moved from a slide deck into construction. On June 17, 2026 the company began work at Moreton Bay in Queensland on the site of a former paper mill.
